Convert pound-force square second/foot to femtogram [fg] Online | Free weight-and-mass Converter

It looks like you mentioned "pound-force square second per foot". This is a compound unit that can be broken down into:

• 
  

  pound-force (lbf): a unit of force

  
  
• 
  

  square second (s²): time squared

  
  
• 
  

  per foot (ft⁻¹): per unit length

  
  

What does this unit represent?

It could be a unit for something like mass or inertia-related quantities in imperial units, depending on context. For example, it might show up in equations involving force, time, and length — possibly in mechanics or engineering.

To understand or convert it:

1. 
   

   Pound-force (lbf) is a force unit, where:

   
   

2. 
   

   Second squared (s²) is just time squared.

   
   
3. 
   

   Foot (ft) is length:

Femtogram [fg]

The femtogram is a metric unit of mass equal to one-quadrillionth of a gram.

• 
  

  1 femtogram = 0.000000000000001 grams = 10⁻¹⁵ grams

  
  
• 
  

  1 femtogram = 10⁻¹⁸ kilograms

  
  
• 
  

  Symbol: fg

  
  

Key Facts:

• 
  

  Used in highly sensitive scientific research, including molecular biology, physics, and nanotechnology

  
  
• 
  

  The prefix "femto-" means $10^{-15}$ (one quadrillionth)

  
  
• 
  

  Measures incredibly small masses such as molecules, atoms, and nanoparticles

  
  

The femtogram allows for the detection and measurement of ultrafine masses at the atomic and molecular scale.
